Coils must be checked for resistance before they are fired on a device, and re-checked periodically to ensure the resistance remains the same.

Important information about sub ohm vaping:

Use of sub ohm is not for a novice user and requires more vaping experience to use safely and correctly. This tank will only work with a mod capable of firing sub ohm. Please ensure that your batteries can handle the extra power required and that your mod can handle the amps safely.

In addition to this when using sub ohm coils we advise not to use any e-liquid with more than 6mg nicotine. This is because sub ohm vaping creates much more vapour than usual and may cause the liquid to taste harsh or burnt.
